  • Applications

    Triheptanoin (CAS 620-67-7) is a medium-chain triglyceride used as a lipid-based carrier in pharmaceutical and cosmetic formulations. In pharmaceuticals, it serves as an inert solvent and vehicle for lipophilic drugs and as a component of lipid emulsions for parenteral or enteral nutrition, within applicable regulatory limits. In cosmetics and personal care, it functions as an emollient and lubricant oil that enhances texture and spreadability in creams, lotions, and oils. It is also commonly evaluated as an energy source in specialized nutrition products and as a lipid-based solvent/vehicle for lipophilic actives in topical formulations. In industrial contexts, it may be used as a lipid-based processing aid or solvent in niche formulations.
